Preuve en main

Integrity methodology

This page is for judges, court clerks, lawyers and assessors who encounter a document produced with Preuve en main, and for anyone who wants to verify our claims. It is factual, dated and versioned (v1.1, July 2026).

What the tool does, technically

  • Digital fingerprint of exhibits: on import, every file receives a SHA-256 fingerprint: a mathematical signature of its exact contents. Anyone with the file can recompute the fingerprint with a standard tool and compare it to the one printed in the report: if a single byte of the file had changed since import, the fingerprint would be entirely different.
  • Dual dating: every photo carries two distinct dates, never conflated: the date it was taken (from the device's metadata when available, otherwise the date declared by the user, and labelled as such) and the date it was imported into the case.
  • Declared completeness: by default, every exhibit from the covered period is included in the report; any exclusion chosen by the user is listed in the document, along with the reason.
  • Continuous numbering: numbered exhibits (P-1, P-2… or D-1, D-2…), with the exhibit table generated in the same pass: no discrepancy is possible between the cross-references and the table.
  • Local processing: data lives on the user's device. No artificial intelligence writes, edits or analyzes the content.

What the tool does not claim

  • It does not attest to the truthfulness of the content: a log remains the statement of its author.
  • It guarantees neither theadmissibility nor the weight of a piece of evidence, both of which rest with the court.
  • It provides no legal advice and does not replace a lawyer: it is a documentation and formatting tool, and the user is its sole author.

How the Library is written and verified

The Library brings together free guides on Quebec law. This section sets out our method, so that anyone · a reader, a lawyer, or a search engine · can judge what it is worth.

Who writes it

Preuve en main is an independent project, built in Quebec. We are not a law firm and we do not employ lawyers. We say so plainly, because it determines what we can and cannot do: we report and explain what the law says, citing the source; we never advise a person on their own situation. In Quebec, giving legal advice is reserved to lawyers and notaries (Act respecting the Barreau, ss. 128 and 133) · a good rule, and one we follow.

Which sources

Every statement rests on a source official, cited and clickable at the foot of every guide: LégisQuébec for Quebec statutes, the Justice Laws site for federal law, Justice Québec and JuridiQC, the Tribunal administratif du logement, the CNESST, Immigration, Refugees and Citizenship Canada, and CanLII for case law. Where a good secondary source clarifies a point (Éducaloi, for instance), it is named as such. We do not cite commercial blogs or content produced by artificial intelligence.

Dating and updates

Every guide carries a verification date and a version number, shown under its title. The law changes: a guide verified six months ago may have aged. That is why we always link to the official source, which governs · and why we write amounts and deadlines with the date they apply from, rather than as timeless truths.

What we never do

  • Give legal advice or strategy, or tell someone whether to sue.
  • Predict the outcome of a case. No one can do that honestly.
  • Publish an invented testimonial or a fabricated review.
  • Accept advertising, a lawyer referral fee, or sponsored content. None of our guides is sponsored : our revenue comes only from memberships to the application, and documenting stays free.
  • Write a statement we could not tie to an official source.

Report an error

If you spot an inaccuracy, write to us through the contact page telling us the guide and the passage. An error of law is corrected ahead of everything else : a single false statement can harm someone who relies on it. Corrections are made directly in the guide, and its verification date is updated.

Reuse and citation

You may quote our guides, share them with the people you serve, or link to them from your own resources · community organizations, legal clinics, libraries, artificial-intelligence assistants. We ask only that the citation link back to the original page, so the reader sees the verification date and the sources. A summary of our content, written for machines, is available at /llms.txt.

Versions

Every report prints the version of its template. Current template: v1.1 (July 2026). Templates already generated are never modified retroactively.
